[Q] Rooting 4.0.2.A.0.62, already have an unlocked bootloader. Help?

So folks.
Just reached home with my new phone, an Xperia Arc S LT18a, I believe.
I'm stuck with this firmware 4.0.2.A.0.62 which doesn't seem to have an easy way to get a custom ROM on it yet. Sucks that I didn't read about this before heading out to buy a phone.
I went through one of the guides here and had the bootloader unlocked via Sony's website. However, the rooting instructions didn't work. So searched further and realised the issue.
I've seen people say that they've done it by downgrading to a lower firmware, rooting it and then upgrading the firmware OTA again. Then I read that upgrading firmware OTA with an unlocked bootloader will brick my phone. So I'm not trying that.
Any help on how I could go about this? Simple step by step instructions would be very welcomed, since I don't really know much about flashing various bootloaders and ROMs considering I just bought the phone.
Thanks for reading!

there are many threads relating to this problem....plz read & search before posting....
Well i believe the answer to your questions lie in this Thread ...

Flash the zip I attached to this post through CWM. That's it, you're rooted

Thanks!
I used the above zip file, but from a different thread and got it working. Cheers to both of you!

How can I have CWM on my phone? If I will flash phone I will do it with rooted ROM not stock. For me it's closed circle because I need root'ed device to load CWM on it, and I need CWM to make root.
Can someone explain me it?

With unlocked bootloader, one can easily flash a custom kernel with CWM, then flash the zip file.

I when I rooted my locked bootloader ARC S, I read "The Nutshell Arc Guide" at http://forum.xda-developers.com/showthread.php?t=1304634

What can I do ?

Hi all
Ok it's a long story but I think you guys need to know.
Ok I've got a arc s which isn't rooted and bootloader is locked (i think), running the latest stock rom.
I want to get a different rom like CM9 or CM10 because stock rom is almost unusable but I need to unlock my bootloader and root my phone, but everything I try to do those 2 things just fail for some unknown reason.
I have no idea if the latest stock rom is rootable yet, but I've red up that you don't need to be rooted to unlock the bootloader
( I'm not 100% sure on that).
But when I try to unlock my bootloader my phone won't boot into fastboot mode, (I know how to do it but it just goes into the charging screen).
and when I try to root my phone the program i used just gives me a ton of errors and phone isn't rooted when it's finished.
( I used doomloards ICS rooting method )
So I question is
Is there any rom I could flash in my phones current state because I HATE stock rom, I just can't use it without it rebooting all the time.
If so please post a like to the rom
Any help will be appreciated.

Read the stickies, look in the development section.

Install CWM and flash a Rom for locked bootloaders (eg. JJ`s Hybrid Rom )
P.s. : Have you checked if your botloader is unlockable ? Have you tried to unlock it at sony website ?
And if you realy want to unlock BL and root your phone... do some more reading. You will find at sony website all the info you need to know about how to unlock your bootloader. From there it should be very easy to flash custom kernel and Rom (custom kernel comes with CWM integrated).

Ok well I've looked a bit more at sony's website and found the unlocking bootloader page http://unlockbootloader.sonymobile.com/instructions
But when I entered the code in the dialler, nothing happened...
Also I've found this thread http://forum.xda-developers.com/showthread.php?t=1642480 which looks useful enough but I follows the thread to the rooting pages
and I looked at them they where the same methods I tried before, but it doesn't work, I just get errors and no root
I've had this problem before, when I was trying to root my phone, It just kept failing.
I saw some threads on installing CWM but they all seemed to require root access. so at the moment I'm ******.....

return to stock rom

hi, I did a trade with some here on the XDA for a galaxy nexus. The phone comes with BAMF ROM but I am thinking of returning to the completely stock rom. Since I do not know much information on this phone, I thought I will ask before doing anything stupid.
I am not sure exactly if this is a international or playstore phone (I think it is international) but I do know it is a GSM phone.
Also, it appears to me that the phone is already unlocked (and I think rooted but cannot be sure).
So my question is how exactly should I go through to get the completely stock as I kind of want to try stock JB first. Do I need to relock it and download the image from google (which image as I see there are two version of phone.
I may try different rom in the future so can I just download teh image and flash the rom without relock it? Or I should still lock the phone, flash, unnlock, unroot?
A little bit of background. I am using the phone on T Mobile's network here in the US, so I want to be able to continue using hte phone on the same T MO.
Thanks a lot for all of the helps guys.

Link to the step-by-step, amazing, descriptive guide here

thanks a lot. I follow that thread and I think I have returned the phone to the stock rom.
Quick question, I think my bootloader is still unlocked as when I checked the bootloader, it looks it still says unlocked. Now after I have flashed the stock rom, should I still root it and also install the recovery if I ever plan to play around with the different roms? As of now, when I into recovery, I see the little andrid icon but no selection.
thansk a lot guys.

If/when you want to root and mess with ROMs, you'll be using a custom recovery like CWM. You don't need to flash it until you choose to do those things.

thanks. Would I need to root again? The phone is already unlocked (as I did not lock it again). So, I would just have to root and then flash the custom recovery then?
BTW, I notice there's a very nice tool on the sticky that does everything. I am curious if I use that tool and let say choose to unlock it again or root again and such, would that be any issue? Ie, if it's already unlocked and you run unlock again, would that relock, etc?

You can easily root too if you want to in the future
I think you're talking about the toolkit... Me and others here don't recommend using that... Unlocking/locking the bootloader is easy anyways...

Flashing a custom recovery is part of the rooting process.

Don't use 1-click toolkits. You know how to do it manually, do it manually.

got it, thanks a lot guys. Will have to read up more on the root and flashing rom. Android is still relativly new to me.

Warning: Incoming Noob - AuroraPlay v1.1.0 Install

First and foremost, I apologize for being such a noob.
I don't know what I'm doing here, since this is a place for expert developers, and I am not one.
But, I'm purchasing an Xperia Play very soon, and I ran across the AuroraPlay ROM which apparently speeds up the device a bit (Main Features - Clocked by default to 1.2GHz, Full GPU Hardware Acceleration, Boots in less than five seconds, etc.)
So, I thought, "This is really something, I should think about installing this, it'll surely make games and such a lot more fun on my Xperia Play."
I know the mere basics that anyone knows- unlocking, rooting, roms, kernels, firmware, etc.
But when it comes to getting down and actually doing something more advanced than simply rooting or unlocking a phone, I get cold feet.
What I mean by this, is I'm not completely sure how to install this ROM, and I don't want to brick my phone.
I've seen the installation instructions, though I'm still confused on some parts.
What's an Un/Locked Bootloader? How do I know if mine is un/locked?
How do I "Flash using Flashtool"? or "Root using Flashtool"?
What is X-Parts Recovery? What is ClockWorkMod? How do I use them?
At this point it may seem obvious this isn't for me, but if there is a more detailed tutorial out there for this ROM, that would be EXCELLENT! :laugh:
Again, sorry for the trouble.

Un/locked bootloader is about changing kernel and u can find it with enter *#*#7378423#*#* in phone
And if u have unlocked bootloader u can flash a kernel using flashtool with going to fastboot mode(power off ur phone and hold search button then plug ur usb)
To root ur device using flashtool u should connect ur phone to computer then in flashtool click on opened lock
And x-part is an app that installing recovery for locked bootloader and with recovery u can install roms on ir phone

First and foremost don't think you're a noob, everyone has to begin somewhere.and I don't own an xperia play but the basics are all the same.A flashtool is a program used only to flash roms and kernels but not root your device. For rooting, there are other toolkits, most of them really simple, just plug ur phone and follow the instructions shown.as far as I know, there is no need to unlock the bootloader of ur phone as long as u flash stock based roms but to flash custom kernels and roms,u need to unlock the bootloader and the bootloader for any mobile will be LOCKED by default. Behold.. Unlocking the bootloader can only be done officially and u will forever lose warranty and some other stuff like drm keys,etc..relocking the bootloader is also possible but ur warranty still be void.clockworkmod(cwm) is a custom recovery which gives many more features than a stock recovery and is used for flashing firmwares, kernels,etc,u can see about that on YouTube cuz there are walkthroughs for almost anything.I don't know much about X-parts though.there u go.hope I helped u.hit thanks if I did.

Thanks for the replies.
By the way, is there anything I need to do with my phone before I began the installation process? The phone obviously needs to be rooted, right?
Or can it be done straight out of the box?

If u r gonna root the phone as soon as u open it,there is nothing much u need to do..download all the files beforehand and be sure to double check the model number of ur device.if u really want to flash a custom kernel,u must unlock ur bootloader and as it was said,u won't have the warranty after that.So what I suggest is u use the phone for about 2-4 days and make sure there is no defect in it,just to be sure.So happy rooting!Hit thanks if I helped.

Welcome to the forums!
When I first started rooting and flashing custom roms, the guide on the nxt rom page helped me a lot. Here-
http://forum.xda-developers.com/showthread.php?t=1649368
In the first post, follow the instructions for locked bootloader, and there is a picture guide for how to use flashtool and CWM recovery (the older version of x-parts recovery). Just replace instances of zeus_nxt2_r1.zip with the rom of your choice!
Hope I could help!

xperia play
i love this device but i want jellybean on this device ... can anyone help me out ??

Well.. If the official update has been released, u can download the file and flash it after rooting your device BUT u can also unlock the bootloader and flash a custom kernel and latest custom rom like cyanogen mod and stuff..hit thanks if I helped u in any way

To install jelly bean you need to unlock your bootloader. The touchpads are not working very well though...
About the warranty thing, Sony says this voids your warranty, but I did it anyway a few months after I got my phone, and recently both of my cameras died (not at the same time, but I didn't care about the front camera) and they fixed them for free so maybe they still fix hardware defects (they did it for me). Of course I did re lock my bootloader before giving them my phone but they could know it since they had mY IMEI

Sounds interesting.. They repaired ur phone for free even when they knew u had unlocked its bl?good thing that the flashtools can relock the bl..ur post knocked some confidence into me..

[Q] Bumping????

Hello everyone!
I just don't get it. Can anyone explain to me what's the difference between flashing a bumped rom and flashing the same rom un-bumped? I just don't get the whole point of it! Sorry, but coming from a Nexus device (why have I ever changed!!!) I'm new to these things.
So, other questions would be: what's the point of bumping? What if I don't do it and just go about the usual way: Unlocking the bootloader, rooting and installing a custom recovery and then proceed to flash the appropriate and preferred rom, kernel, etc?
Hope somebody will bear with me and try to explain these things to a newcomer
Thanks

Because
1) Bumping is used to trick the bootloader into thinking that the boot.img is authentic and from Official LG Sources
2) Without bumping you could have to constantly run fastboot boot boot.img (an example of this was CM11 when it first started development)
3) Bootloader cant be unlocked at this time so we rely on a bootloader exploit in order to run custom recovery
4) Its all about the authenticity. If the LG bootloader does its security checks and anything fails then the system doesnt boot

Thanks for the very easy tuo understand explanation. I should have thought that the problem was unlocking the bootloader! Guess I'll have to with the Flow and bump my new phone. I wish I asked my Carrier for an HTC M8

simple answer: bump is the only way to unlock g3 bootloader.
all roms are bumped whether displaying [BUMPED] or not.

Ok, so by simple logic, once I have installed, either via bump, flashify or ADB a recovery, I can pretty much flash any rom that is appropriate for my model no, isn't it?
So there is one more question I have: what is the purpose of unlocking the bootloader and then what could be the problems if I don't? If everything I flash for this device (TWRP, roms, kernels, etc) is, by default, bumped, what's the purpose of installing bump at all?

You're making it so much harder for yourself dude.. There really is only one way to install custom ROMs and that is by Bumping your phone. That's it.
You go here and read the entire topic. Don't miss a single thing.
Then go here and flash the zip for the latest TWRP.
After that you can install any ROM in the OG and Android Development section.
That's all there is to it. You can read in those topics for more information about what they do.

if you dont bump, then you wont have twrp lol.
you cant flash any roms anyway, you'll potentially brick/soft brick your phone.
roms etc are bumped because they have a patch script implanted to run on the phones correctly.

OK. Got it! It took a while, but I give up!
Thanks for the help. Coming from the most easy to play with phones (only Nexus so far, but I hate the N6), it isn't easy to have to deal with more stuff than usually needed and hence more complications than usually had.
I thought that, after rooting I could flash TWRP via flashify or rom toolbox and then I would have TWRP without BUMP, but it must be that I'm missing something, if you say I MUST bump my phone to install TWRP.
Thanks and see you around

What exactly do you mean "How to bump"??? Bump and loki are bootloader exploits that allowed us to boot TWRP and all the benefits TWRP offers... On the user side of things you don't "Bump" anything- the Roms, Kernels, and recoveries are "pre-bumped" by the developers and 99.9% of the time they will say whether or not it is "bumped" or "lokied" although loki is really outdated and I doubt you'll encounter it. So in a nutshell we(the user) doesn't "Bump" anything and just make sure to really read before flashing
